Quantum computer investment race heats up, but experts say there is still no use for it
Competition to invest in quantum computers is intensifying as the U.S. government and major big tech companies point to 2028-2030 as a turning point for practical use. Researchers say current systems are too small and too error-prone, with no confirmed case of solving problems useful for industry. Companies and governments are setting roadmaps, while academics debate gaps between claims and technology, and highlight error correction as a key hurdle.

Academics spar over Microsoft Majorana 2 quantum chip claims
Academics have raised questions over core technology behind Microsoft’s Majorana 2 quantum chip. University of St Andrews physicist Henry Legg said Microsoft has not proven the existence of topological qubits, arguing that tuning procedures, code errors and missing data undermine the company’s claims. Microsoft rejected the criticism, saying it stands by its results and roadmap and that its work has undergone independent verification through a DARPA benchmarking initiative.

Microsoft unveils next-generation quantum chip Majorana 2, targets commercial quantum computers by 2029
Microsoft has unveiled its next-generation topological quantum chip, Majorana 2, and set a goal of building a scalable quantum computer with commercial value by 2029. The company said development automation using artificial intelligence has brought forward the timeline for commercialisation significantly from prior expectations. It said Majorana 2 improves qubit reliability by about 1,000 times and can maintain quantum states for an average of 20 seconds and up to nearly 1 minute.
